Kent's ISS photo from last night
He also caught Collinder 71, a large star cluster around the center star in the belt. Rare seen from the city or suburbs and rarely noticed by telescope users who are using tight FOVs. Relax your eyes

Kappa Leonis update
Sky tools has the separation at 2.4 arc seconds as of 1975. Not sure where it is now. Does 0.4 more than 2 make a difference? I don't know. I might buy 2.4 for 5 magnitudes difference but still one of

Lunar observing last night
I had time at the end of the evening yesterday to observe the Crater Aristarchus and the plateau it sits on. Using the 5 inch with a 9mm orthoscopic eyepiece I could detect stripes of dark material on

Interesting find. 19th Century Petzval portraiture lens. Basis for my 4 inch Televue's optics.
The Petzval lens was designed in the 1840's as a fast focal ratio (f3.4) photographic portrait lens. 4 elements (two sets of spaced doublets), it could reduce portrait exposure times to less then a mi
